Well, this is certainly interesting...
It shows the correct & expected score of 97.97 at depths 14 and 15. Then the score gets overwritten. This can happen and is allowed, but when overwritten by a lower score, the TBs should activate once again and keep overwriting any non winning score.
This is quite odd.... the only thing I can think of is that the best move is the only move (which it is in this case) and also the PV move (which it is), and thus gets searched regardless, and the searched score gets reported.
Under previous code, this could happen resulting in an unusually low score from time to time. However, because the moves must be the PV in order for this to occur, there was no real harm as the engine would (and still does) follow the optimal path. If it somehow switched off the optimal path, it would be corrected immediately via hash.
However, I recently added code, which was supposed to correct the visually anomalous low scores. And I can not see any reason for that to not currently be the case.
TLDR: Optimal play should not be an issue, since the only time this can happen is if the best move is already the PV move. Irregularly low score should not appear unless PV path is *only* winning path. Irregularly low score shouldn't appear at all now, or at the most only momentarily. Will investigate further...
Joe , it does appear to be a bug of some sorts. Stockfish does not behave this way. Black-Diamond, based on Crystal does ( behaves same as Crystal).
I used 6 man EGTB - 510 files.
This how the functional equivalent SF behaves:
